SPECIFICATION forming part of Letters Patent No. 781,479, dated January 31,1905.

i y Application filed l(l'uly 2, 1904. Serial No. 215,127.

' a citizenl of the United States, residing at Troy,

in the county of Miami and State of Ohio, have invented av new and useful Improvement in Egg-Preserving Cases, of which the following is a specification.

My invention is in the nature of a novel egg-preserving case. It is an improvement lin the class of egg-preserving cases'in which nnions or journals, whereby the case turned from time to time to prevent lkfrom settling to one side of the shell,

1&5 in which position it soonvspoils.

invention `consists in the novel construction and arrangementof the cases in series one above the other in an upright frame vvith means for removing the cases from the frame 'and inserting them again .and for giving access to the cases and for fixing the positions of the cases in the frame;

l It also consists in the construction and arrangement of the cell-partitionsv for holding and spacing the eggs in such manner'as to permit' them to be compactly stored, lirmly held,

and thoroughly ventilated and to permit them to. be turned over without shock or jar, as will be hereinafter fully described with reference to the drawings, in which-'- Figure lis an end view, partly in section, on line l I of Fig. 2. Fig. 2 is a side view. Figs.' 8 and 4 are details of the cell-forming partitions, and Fig. 5 is a detail of the locking-bar. In the drawings, A represents a suitable base upon which are erected'two verticallyparallel standards B B, connected at the top .by a cross-bar C. In the adjacent faces of these standards are formed vertical grooves with bearing blocks ory stops a at suitable i'ntervals which form bearings for the trunnions b Z) of the.rotaryadjustable cases DD D. These trunnions are mounted on cross-bars at the ends of the cases, which cases are other- Wise open at the ends for purposes-of ventilation. There may be any number vof these cases arranged in vertical series one above the other, each having its trunnions resting in the grooves of the standards upon the bearings a. Each case :is composed of four equal and square sides with open ends, one side D of each case being made removable and being de- 'tachably secured by means of a spring locking-bar d, pivoted in the middle and having keyhole-slots ci' at the end which are adapted to receive the heads of'screws or headed pins Z2 cl2, whose heads pass through the large ends of the keyhole-slots CZ. When the heads `pass throughl and the bar al is turned about itspivot, the edges of the narrow ends of the` slots pass under the heads of the screws, and

thus lock thev removable side of the casein place to closethe same. The removability of this side of the case permits the cell-partitions and the eggs to be putinto ortaken out of the case. By the mounting of the cases on horizontal trunnions the cases, with the eggs, may be turned partially over', and the position of the eggs are thus changed as often as may be desired. To fix the various positions of the cases, pins or set-screws E are tapped through one of the standards and are made to enter seats e in the ends of the case, and thus hold the latter to any of its four posi` tions to which it may be turned. To put the cases into or takethem out ofthe frame,

lateral outlet-slots c c are formed in the standards, which lead into the grooves in the adjacent faces of the standards.` Theseou tlets are located a distance above the bearing-blocks a less than the difference between a radial line passing through the angle of the caseand a radial line passing through the side of the case midway between the angles. l The bearingblocks a are also spaced vertically kin the.

grooves of the standards, -so that the cases Ymay revolve freely without touching each If,`how ever, any

other at their outer angles. case is turned so that two of its sides are horizontal, then the casemay be lifted high enough (see dotted lines in Fig. l) so that its trunnions can rise to the outletso before such case strikes the next one immediately above it.

This permits the cases to be arranged in ver- TOO Figs. 3 and 4,) which is designed with reference to preventing the eggs from being jolted or individually shifted while being turned and also with reference to securing the most compact storage of the eggs and a free ventilation or passage of air through the same. These cell-partitions are simply sheets of woven wire crimped or bent into zigzag angles and having these angles connected by stay-bars ff at the ends, which bars or braces by uniting the apices of the angles prevent the spreading out of the partitions, and thus keep them within the limits ofthe sides ofthe case. The parallel channels of each partition are in depth equal to about one-halt' the thickness of an egg, so that it takes two partitions to form a complete set of egg-channels. When the cell-partitions are put in the case in the relation shown in Fig. 4, the angle of one partition cooperates with the angle of the next adjacent partition, so as to form complete parallel chambers in which the eggs are packed, and when the eggs are so placed each egg is held at four points by the tangential contact of the sides of the two cell-partitions with a somewhat elastic grip that prevents breakage from individual movement of the egg and causes all ofthe eggs to be held alike and to be turned alike when the cases are rotated on their trunnions. There is therefore a special correlation between the form of cell-partition and the rotary character of the case which prevents all shock and jar and individual movement of the eggs. As the cases are open at the ends, it will be seen that the partitionbraces ff not only act to prevent the spreading of the crimped partitions, and thus prevent the crushing of eggs from the superincumbent Weight of the eggs above, but it will be seen that these braces extend directly across the middle lineot' the rows of eggs and keep them from dropping out the ends of the channels, which is an important result when the ends of the cases are left open for ventilation, as shown.

It' desired, the case may be made with only one of the receptacles D, or it may, as before stated, have any number of the same arranged in vertical series, which secures great economy of floor-space and easy inspection and access.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-` 1. An egg-preserving case consisting of a vertical series of receptacles having square sides, one of which sides is made removable, and having open ends with cross-bars provided with trunnions; combined with a supportingframe composed of a base and two vertical and parallel standards having vertical, longitudinal grooves in their adjacent faces with bearings in the grooves for the trunnions and lateral outlets for the grooves above the bearings to permit the receptacles to be independently removed substantially as andfor the purpose described.

2. An egg-preserving ease consisting of a vertical series of receptacles having square sides, and trunnions at the ends, combined with a supporting-frame composed of a base and two vertical and parallel standards having vertical, longitudinal grooves in their adjacent faces, with bearings in the grooves for the trunnions and lateral outlets for the grooves located above the bearings a distan ce less than the difference between the radial line passing through the angle of the case and a radial line passing through the side oi the case midway between the angles, substantially as and for the purpose described.

3. An egg-case mounted onahorizontal axis to rotate and provided with cell-partitions formed of woven wire arranged in zigzag form forming channels of half the thickness of an egg and having their apices connected by staybraces to prevent the crimps from spreading and for holding the eggs against moving endwise out of the channels substantially as described.

4. A cell partition made of angularlycrimped woven wire, the crimps forming pai'- allel channels of haltl the thickness of an egg and maintained in zigzag form by stay-braces at the ends and two of said partitions forming one complete set of egg-channels substantially as described.

5. An egg-case having four square sides with open ends, one of the sides being made removable, and cell-partitions formed oi woven wire crimped into zigzag channels of half the thickness of an egg and two of said partitions forming one set of the egg-channels and having staybraces at their ends to hold the eggs in the channels substantially as described.
